Colorado Coolwear also produces
a neck wrap that uses the same technology as the Coolvest
which provides a similar cooling effect when worn around the neck.

Before use, soak them in water for a few minutes, wring them out and tie them loosely
around the neck like a bandanna. At break time rewet them for a minute or so if
necessary, then wring out slightly and reuse time after time. Unlike the
Coolvest which
cools the entire trunk of the body, the neck wrap cools the blood moving through
the main arteries of the neck.
